Researchers reconstructed charge density from diffuse X-ray scattering of non-periodic samples. By assuming an artificial superlattice, direct crystallographic methods solved the phase problem for isolated particles, like gold nanoparticles.

Area of Science:

  • * Materials Science
  • * Crystallography
  • * Nanotechnology

Background:

  • * Reconstructing charge density from diffuse X-ray scattering is challenging for non-periodic samples.
  • * Existing methods often require crystalline or periodic structures.

Purpose of the Study:

  • * To develop a method for reconstructing charge density from diffuse X-ray scattering of isolated, non-periodic samples.
  • * To apply numerical direct methods of crystallography to solve the phase problem in such systems.

Main Methods:

  • * An artificial superlattice was assumed for isolated samples.
  • * Numerical direct methods of crystallography were applied to the continuous diffuse scattering distribution.
  • * The method was tested using simulated soft-X-ray transmission speckle patterns of gold nanoparticles.

Main Results:

  • * Successful reconstruction of charge density from diffuse X-ray scattering was demonstrated.
  • * The phase problem was solved for simulated data of a two-dimensional gold ball array.
  • * The method shows promise for analyzing scattering from individual nanoparticles and macromolecules.

Conclusions:

  • * The proposed method enables charge density reconstruction from diffuse X-ray scattering of non-periodic samples.
  • * This approach is applicable to individual macromolecules and inorganic nanoparticles that cannot be crystallized.
